Suburban Nt Series NT32AE Parts Diagram · Replacement

Furnace · 5 assemblies · 10 diagram sheets · 54 parts · by Andrew Strick, mobile RV technician

OEM exploded parts diagrams for the Suburban Nt Series NT32AE RV furnace: 5 assemblies (Replacement, Exploded View › Combustion Chamber, Exploded View › Burner Assembly, Exploded View › Cabinet Assembly, Exploded View › Blower Assembly) and 54 manufacturer part numbers. 11 parts are marked as superseded — the description gives the replacement number to order instead.

The rating plate is on the furnace chassis — slide the unit's front panel off or look just inside the exterior access door. Suburban models (SF-30F, NT-34SP …) changed burners and boards over the years, so the serial number's date range matters as much as the model.
